I am never going to be one of those that believe that altcoins are not worth investing your money on, because altcoins play a big part on my journey to success in the past years, the only thing here is understanding the difference between altcoins and Bitcoin investment, and the best advice is to never put all your eggs into one basket.
Altcoins investment Facts.
1. Most altcoins don't ever see a new all time high again, once they do well in a bull market it's over for them.
2. Most altcoins won't survive in a bear market, before a new bull market gets here they would have died.
3. It's only in altcoins space that scams exists, there are many new projects that are showing up only to take peoples money and exit liquidity on the investors.
4. New altcoins brings the biggest ROI but they are also the most risky investment, if they go down they go down hard and fast.
Bitcoin investment Facts.
1. There is no reason to be scared of scam when investing in Bitcoin, it isn't a smart contract enabled project like Ethereum.
2. Bitcoin always makes a new all time high.
3. You only lose if you sell your Bitcoin, unlike altcoins that can go down and never go up while you holding them.
4. You need good amount of money invested in Bitcoin to make better ROI, Compared to altcoins, investing only 100$ in a good alt can bring you better ROI than investing 100$ in Bitcoin.
In fact, investing in altcoins as you mentioned is basically very high risk, and it has been proven that many people suffer losses due to investing in altcoins, but most people always have a greedy nature and want to get big profits, including myself, I also always have a greedy nature, because I also always invest in altcoins, but of course I am ready to take the risk if I experience a loss investing in altcoins.
In fact, investing in Bitcoin requires a large amount of capital because with small capital it will be difficult to get large profits, but I also invest in BTC, there is no doubt because only investing in BTC is the safest and I myself always invest large.because I believe investing in btc is the safest as you mentioned.
However, investing in altcoins and BTC is certainly not free from risks, the most important thing is to only invest money that you are ready to lose. and in this case it depends on an investor's knowledge in managing their assets.
